What would he show as?

[HappyDayz]

Having retired him at the beginning of the year and getting a new horse looking like a distant dream I thought we could have a pop at in hand showing. Only thing is I know nothing about this! I am guessing I could do in hand veteran classes as he is 16 but what else? He has many scars due to his past. If it is possible to show him, what does he wear, flat noseband, what browband, pain or ribbon? What do I wear from a hat to shoes? I really know nothing about showing! HELP! Hopefully there will be a picture below or someone can help me on that too!!

You wear the same regardless of what class you enter.
Tweed jacket
Shirt and tie
Trousers in a contrasting colour to horses legs,
Jod boots or similar smart shoes/boots that you can run in
For women hair should be in a bun and net
You should wear either a navy velvet riding hat, a navy beagler or a trilby.

Hard to say what class from that photo, do you have a side on photo at all? (Ridden is fine)
